Preliminary Technical Data GENERAL DESCRIPTION
This document describes the differences between the ADSPBF522C/ADSP-BF525C/ADSP-BF527C and the ADSPBF522/ADSP-BF525/ADSP-BF527 standard product. Please refer to the published ADSP-BF522/ADSP-BF525/ADSP-BF527 Revision PrC datasheet for general description and specifications. This document only describes the exceptions to that datasheet. The ADSP-BF522C/ADSP-BF525C/ADSP-BF527C adds a stereo CODEC to the standard product and changes the package labeling.
ADSP-BF522C/ADSP-BF525C/ADSP-BF527C
In normal mode, the XMI/MCLK oscillator is set up according to the desired sample rates of the ADC and DAC. For ADC or DAC sampling rates of 8 kHz, 32 kHz, 48 kHz or 96 kHz, MCLK frequencies of either 12.288 MHz (256 x FS) or 18.432 MHz (384 x FS) can be used. For ADC or DAC sampling rates of 8 kHz, 44.1 kHz or 88.2 kHz, MCLK frequencies of either 11.2896 MHz (256 x FS) or 16.9344 MHz (384 x FS) can be used. In USB mode, the XTI/MCLK frequency is only 12MHz allowing for ADC and DAC sampling rates of 8 kHz, 44.1 kHz or 88.2 kHz. The CODEC can operate with power supplies as low as 1.8 V for the analog part and 1.8 V for digital port. The maximum voltage is 3.6 V for all power supplies. The device is controlled by a 2- or 3-wire serial interface which provides access to all features including volume controls, mutes and extensive power management facilities.
STEREO CODEC
The CODEC in the ADSP-BF522C/ADSP-BF525C/ADSPBF527C is a low power, high quality stereo audio CODEC for portable digital audio application. It features two 24-bit A/D converter channels and two 24-bit D/A converter channels.
